Aucklanders returning home from work are warned to expect huge traffic delays as crowds head to the America's Cup race on Wednesday afternoon.
St Patrick's Day celebrations and Emirates Team New Zealand on the cusp of winning the cup will see spectators gather along Auckland's waterfront to watch the action.
On-land viewing will also see crowds of people heading towards North Shore beaches - including Cheltenham Beach, Narrow Neck Beach and others in the East Coast Bays.
Transport officials are urging commuters to plan their travels in advance and expect delays across the city.
"Combining racing fans and people enjoying St Patrick's Day, the roads and public transport will be busy, extending the city's evening peak time travel congestion," an AT spokesperson said in a statement.
"Give yourself a bit more time to get home. Expect more customers on public transport in the evening peak, longer boarding times and delays getting in and out of the city."
Ferry customers may experience delays and longer sailing times particularly during and after racing.
"Consider taking the bus home instead of the ferry," AT said.
"Plan your bus ride home using the Journey Planner in the AT mobile app.
